You’re shopping for a new laptop case, trying to adjust your display settings for the perfect clarity, or maybe you’re just curious. Knowing your laptop’s screen size is one of those simple but essential pieces of information. It’s not always obvious, and you certainly don’t need a ruler to find it. Let’s walk through a few simple ways to measure your screen, both with and without turning your device on.
The Easiest Way: Check Your Laptop’s Model Number
Often, the quickest path to your screen size is through your laptop’s model name or number. This information is usually on a small sticker on the bottom of the device. Look for a model number that might include a two-digit number followed by a set of letters, like “HP 14-dq1000” or “Lenovo 15IMH05.” That number—the 14 or the 15—typically represents the screen size in inches. A quick online search of that full model number will confirm the exact specifications, including the display size.
Physically Measuring the Screen Yourself
If you don’t have the model number handy or your laptop is off, you can measure it the old-fashioned way. Grab a soft measuring tape. It’s important to measure only the viewable screen area, from corner to corner. Do not include the plastic bezel (the black or colored frame) around the screen. Place your tape at the top-left corner of the glass and stretch it diagonally to the bottom-right corner. The measurement in inches is your screen size. Most laptops are 13, 14, 15, or 17 inches.
Finding Screen Details in Your Computer’s Settings
Your operating system can also provide this information. On Windows, go to Settings > System > Display. Scroll down to “Scale & layout” and look for “Display resolution.” While it won’t state the size directly, a resolution like 1920×1080 on a standard laptop strongly suggests a 15.6-inch screen, while 1366×768 is common on 14-inch models. On a Mac, click the Apple logo in the top-left corner, select About This Mac, and then click “Displays.” It will show you the resolution and often the specific model name that you can look up.
With these methods, you can confidently find your laptop’s screen size in just a moment. Whether you’re making a purchase or just satisfying your curiosity, it’s a handy piece of knowledge to have.
